Provided Methods

fn checkpoint_name() -> String

Return an unique name as the container for your data.

fn from_checkpoint_n(db: &DbConnection, n: i32) -> Result<Self>

Load from the specified checkpoint n (ordered by create time).

fn commit_checkpoint(&self, db: &DbConnection) -> Result<()>

Set a checkpoint

fn restore_from_checkpoint(&mut self, db: &DbConnection) -> Result<()>

Restore state from the latest checkpoint.

fn get_number_of_checkpoints(db: &DbConnection) -> Result<u64>

Return the number of available checkpoints in database.

fn restore_from_checkpoint_n(&mut self, db: &DbConnection, n: i32) -> Result<()>

Restore state from the specified checkpoint n (ordered by create time).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
